What do we mean by one-stop service?

COMPLETE SUPPLY CHAIN INTEGRATION

Supply chain integration can also be called OEM one stop service, In addition to metal processing milling and turning, we provide integrated supply chains from materials to other processes, such as grinding, plating, heat treatment, surface treatment, assembly, packaging and through the complete incoming inspection mechanism in our factory, and regularly annual supplier audit, to ensure what we provide to our customer are in stable quality.

What OEM one stop services Heng Chang Precision Machining can supply chain integration provide?

Diversity materials

Ⅰ. Forging

Cold forging, hot forging, warm forging, aluminum forging, copper forging, etc. It is suitable for the production of large batches of parts. After forging, it would be processed by a turning lathe and milling machine to maintaining the original strength characteristics of the material.

. Casting

Precision casting, sand casting, gravity casting, aluminum die casting, copper casting, dewaxing casting, etc. It is suitable for the production of a certain amount of parts and would be machined by a turning lathe and milling machine after casting. The material strength of this method is relatively insufficient.

. Extruded Profiles

Round bar, hexagonal rods, aluminum extrusion, pumping, threaded rods, plates, pipes, etc. Multiple types of material reduce unnecessary processing time waste and achieve cost optimization
